T 0 all whom it may concern:

Be it known that I, WILLIAM ERAsTUs VliLL'iAns. a citizen of the UnitedStates,

A novel piston, serving also as a valve rotates as it reciprocates, andthe invention resides chiefly in the piston and the means foreausing itsrotary movement.

Reference will be had to the accompany ing drawings in which- Figure 1is a vertical section of the engine on line 1---1 of Fig. 2 as relatesto the sec tion through the ports. Fig. 2 is a plan section on line 2 -2of Fig. 1. Fig. 3 is a plan section with the outside broken away showingonly the position of the ports when closed for compression and tiring.Figt/l is a plan cross section on line 4.-4 of Fig. 1 being: at the topof the helical gear ring that revolves the piston. Fig. 5 1s a plan ofhelical gear ring alone, but with part hrolten oil for lack of space ondroning. Fig. (3 is a plan section on line (S 15 Fig. l of a part ofprojection 14 showing the grooves 33. Fig. 7, Sheet 1 is an elevation ofthe p ton. half size.

The drawings show What is known as a four cycle gas engine but thisvalve motion may be timed for any cycle of explosions.

In the drawing 1 indicates an ordinary crank shaft mounted in anysuitable bearings in the frame or crank case 2. The crank 3 is connectedto any suitable connecting rod 4 that is provided with a ball head 5connected by any suitable socket joint 6 lo a piston 7 packed by anysuitable means or rings 8 into a cylinder 9 suitably cooled by any meansor by the Water spaces 10 incloscd at the sides by the jacket sectionsll.

The cylinder head is made by soap or plug cylinder by screws 1.3 ahdprovided with a projection 14 extending down into the cylinder leavingan annular groove or space 15 and air engines, compressor and pumps andthe like.

12 suitably secured on the top of the around the projection 14. andbetween it and the inside of the cylinder at the top portion of thelatter. In the space 15 at the top of the cylinder there revolves andreciprocates a thin tubular or sleeve extension 16 of the piston 7. Inthe side of this tube or sleeve end 1 3 of the piston there are slots orports 1.? here shown as four in nurnhen These slots 17 are closed at.the top by connecting parts 18. The revolution of the piston causes theslots 7 to register at the required times with the intake ports 19 andthe exhaust ports :10 in the cylinder wall.

The lower end of the piston is formed into a skeleton frame 21 leavinga. connecting ring section 22. The purpose of this frame is to providebearing slots 23 by means of which the piston is revolved as desiredregardless of its position of reciprocation. The slots 23 are enteredand driven in a miary direction by projections 24 of a helical gear riiwmounted to revolve concentric with the axis of the cylinder and locatedbe tween the crank case and the cylinder end. The helical gear 25 isprovided with flange rings 26 which articulate in the crank case and thecvlinder end. and serve to keep the ring concentric with the cylinder.

The helical gear ring 25 is driven by a helical pinion 27 mounted upon aside shaft which corresponds to the general term of a two to one shaftin the Otto cycle engine practice. This shaft, may be driven by anysuitable means but it is here shown as being driven by sprockets 3i} and37 through a chain 39 from the crank shaft. The tin-ling of shaft 28 ismade two to one only for convenience of making it the cornrnutator shafttiming the ignition, but the ratio of travel of the helical ring 25 andpinion 27 may be made as desired by varying the design of the helicalgears.

The ,gnearing here shown is intended to revolve the piston one fourth ofone revolution to two revolutions of the crank shaft, but this may beincreased or diminished as desired and in making such variations, thenumber and width of the slots in the tube or sleeve end 16 of thepi tonand the we haust. and intake ports ti) and "20 must be changed to suitthe changes thus made.

The slots 17 are shown as extending vertically in a straightline thelength of the stroke plus approximately the vertical length of thecylinder ports, and thus the time that any port open is due to the timeconsumed by the slots 17 in revolving past the ports in the linder wall.This is a great desiiileratuin itpermits any timing of the valveopenings that can ordi narily be secured by any other valve mechanism.

Making the ports in and 20 Wider or nal rower or l cating them aroundthe cylinder wall in proper position in relation to the period ofrevolution of the piston makes the timing of intake and exhaust as desired so long the cylinder is given a uniform rotary speed, as is hereshown The intake ports 19 are all connected by the passage 29 to theintake pipe connection 30 whereat connection is made to the carburetoror source of intake supply. The exhaust ports 20 are all connected bythe passage 31 to the exhaust outlet 3:? Where a suitable exhaust pipemay be attached. A spark plug furnishes the ignition by any suilableelectrical means. A, vent cock 34 is prm virled to release compressionwhen desired.

The sleeve or tube end 16 of the piston fits pretty closely into theannular space around the projections 14 of the piston head to prevent asmue'h as possible combustion taking place Within. the annular space asit is intended that what little gas enters here shall be spent gas Forsafety against clogging with carbon and lubricating oil a series ofsmall grooves 35 extend down the sides of the projection 14. See Figs. 1and 6.

An important. advantage is obtained by the sleeve or tube extension ofthe piston inclosing the combustion chamber, this construction kee ingthe tire away from the lubricated our aces at all points save at thenarrow ports 17 in the tube and at the spent as top space of the annularring space 15. L ince the piston is constantly revolving the space openthrough the slots 17 to the ln bricated "wall of the cylinder is onlymomentarily exposed or in other words the exposures of slots 17 aredistributed over a considerably wider space of the cylinder wall leavingless time of intense heat on. any one spot.

The cage or frame extension 21 with its slots 23 of the piston 7 may bemade into a more or less complete ring and be provided witha series ofslots or teeth in which the teeth of the helical pinion may work 4.4thereby eliminating the helical gear ring 25 but with this constructionthere is added weight to the reciprocating piston load.

The tube end 16 of the piston may be a separate piece and properlysecured to the piston head. 21 of the piston may also be a separatepiece made of a malleable metal and very light.

A kind of metal may he used for this cage or 1 The cage or frameextension.

frame 21 that might not be permissible for the upper sectional thepiston, as no combustion occuns in contact with this frame part 21.

Suitable oil grooves and holes not shown in the drawing may be made toallow the splash lubrication of the crank case to oil all the. workingsurfaces. Oil grooves and pockets may be so made in the cylinder andpiston surfaces thal by the rotating reci roeating movement of thepiston any desired amount of oil may be carried up to lu-- bricate thesleeve or tube end 16 of the piston.

By arranging a plurality of intake and exhaust ports and a plurality ofslots in the tube or sleeve end of the piston, a large valve opening maybe secured while at the same time requiring only a small amount ofrotary movement of the piston. Hence with my construction one revolutionof the piston is sullicient for 8 or more revolutions of the crank shaftand this may be increased as desired. The drawings are made to requireone revolution of the pist n to revolutions of the crank shaft ye; agood form would be twice that namely one revolution o'l the piston to 16revolutions of the crank in which case there would then be requiredslots in the piston tube and S intake and exhaust ports. liy lesseningthe number of revolutions of the piston relatively to those of the crankthe friction in the eyliir der is lessened.

The long sleeve or tube end of the piston permits the ports to be openedat any point of the stroke and further the thin tube walls are directlyin contact with the cooled cylindcr wall thereby being cooled which doesnot happen when a long fine is made in a sectionof a long piston as thena large area is open to be overheated by the combustion therein.

What I claim is:

1. In an engine of the class described, the combination with a cylinderhaving lateral ports of a rotary rcciprocatin piston provided at one endwith av tubu or extension having lateral port openin s in position toregister with said ports as the piston rotates, and at the other endwith a longitudinally grooved extension, and a circnmferentiallytraveling piston rotating device engaging in said grooves, and impartingits own mo tion thereto.
